[0003] With the rapid development of automation technology, automatic bearing press-fitting equipment has gradually become an important means of improving production efficiency and product quality. However, existing automatic bearing press-fitting equipment still has some shortcomings in design and application.

Beneficial effects

[0016] In the present utility model, by integrating the bearing loading assembly, the bearing conveying assembly and the bearing pressing module, an automated process from loading to pressing of bearings is realized, which significantly improves production efficiency; compared with traditional manual or semi-automatic installation methods, the automated pressing mechanism can greatly reduce manual intervention and shorten the production cycle.

[0017] In this utility model, the bearing conveying device adopts a double-layer structure design with a first conveying slide and a second conveying slide, making the bearing conveying path more compact and reasonable. This design not only shortens the bearing conveying distance and reduces the conveying time, but also optimizes the equipment layout, effectively reducing the space occupied by the conveying mechanism, making the overall equipment volume more compact, and facilitating layout optimization and space utilization at the production site. At the same time, because the first and second conveying slides can operate simultaneously to achieve rapid reset, the possibility of interference between the bearing conveying device and the bearing press module, causing damage, is reduced.

[0018] In the present invention, the floating connection between the various components of the bearing press-fitting assembly is adjusted to make the two fit tightly and stably; to avoid as much as possible the situation that the positioning parts and the connecting parts are not fully calibrated with the positioning tool and the workpiece on the positioning tool during the bearing press-fitting, resulting in tilting and causing the bearing to be unable to be accurately pressed into the position where the bearing needs to be pressed in the workpiece; so that the bearing, the bearing press-fitting assembly or the positioning tool can be avoided as much as possible from being damaged during the bearing press-fitting, so that the device is not likely to cause damage to the equipment and parts during the press-fitting process.

[0019] In the present invention, the cooperation of the floating installation space and the floating core shaft allows a certain degree of adaptive adjustment during the press-fitting process; when the bearing contacts the workpiece, slight deviations that may be caused by factors such as material hardness and surface flatness can be automatically adjusted in position through the floating cooperation between the connector and the connecting part, ensuring that the press-fitting force is evenly distributed, thereby improving the accuracy and consistency of the press-fitting.

[0020] In the utility model, by setting the floating elastic ring, the small position deviation and assembly error of the bearing can be automatically calibrated during the press-fitting process; the accuracy of the press-fitting is improved, and the stability of the press-fitting process is enhanced, thereby avoiding as much as possible the poor press-fitting effect and damage to equipment and parts caused by assembly errors; at the same time, after the press-fitting is completed, it can also be reset by the floating elastic ring.

[0021] In the present invention, through the arrangement and cooperation of the floating fitting space, the second floating spring and the ejector pin, the ejector pin can be fine-tuned when subjected to external force or encountering unevenness, thereby improving positioning accuracy and achieving better press-fitting accuracy and quality.

[0022] In the present invention, the diameter of the mating portion is smaller than the diameter of the connecting shaft, and the diameter of the mating portion corresponds to the inner diameter of the bearing inner ring; the diameter of the positioning portion is smaller than the diameter of the mating portion; thereby, during the press-fitting process, when the mating portion is retracted into the floating fitting space, the ejector pin as a whole can be relieved of its influence on the bearing, thereby preventing the bearing from being affected by the ejector pin during the press-fitting process.

[0023] In the present invention, the bearing grasping portion forms a bearing grasping space through the expansion and contraction of the third floating spring, thereby realizing automatic grasping and releasing of the bearing; during the press-fitting process, as the connecting shaft moves, the bearing retaining ring and the ball plunger will adjust their positions accordingly, first smoothly grasping the bearing, and then continuously pressing down after grasping the bearing; since the bearing retaining ring is continuously pressed down during the press-fitting process, the bottom of the bearing retaining ring will abut against the workpiece or the positioning tooling, causing the bearing retaining ring to rise relative to the connecting shaft while the third floating spring is compressed. At this time, the ball plunger contracts as the bearing retaining ring rises under the force generated by the contact bearing, thereby releasing the bearing and completing the press-fitting process; the bearing retaining ring is reset under the action of the third floating spring after completing the press-fitting process; this design simplifies the bearing loading process and improves the degree of automation.

[0024] In the present invention, by means of the pressure sensor and the detection displacement sensor provided on the bearing press-fitting module, when the bearing press-fitting drive device drives the bearing press-fitting assembly to perform press-fitting work, the process can be monitored based on the data provided by the two sensors; the bearing press-fitting process is completed by the bearing press-fitting assembly within a certain applied pressure range and a certain displacement range, thereby not only ensuring the quality of press-fitting, but also reducing the possibility of equipment damage as much as possible.

[0025] In the present invention, the movable parts of the first conveying slide and the second conveying slide both move in the horizontal direction, so that the bearing press-fitting assembly moving in the vertical direction can better and more accurately grasp the bearings on the bearing conveying tooling.

[0026] In the utility model, the bearing loading assembly realizes the automatic storage, grabbing and conveying of bearings; no manual intervention is required, which reduces labor costs and also reduces the labor intensity of workers; it can also continuously take out the bearings from the storage mechanism and convey them to the conveying tooling, ensuring the continuous operation of the production line, greatly improving the degree of automation of the production line, shortening the production cycle, and improving production efficiency.

[0027] In the utility model, the automatic circulation feeding of bearings is realized through the cooperation of the bearing storage turntable and the bearing storage driving device; when the bearing of a certain bearing material column is taken away, the turntable continues to rotate, and the new bearing material column automatically moves to the material taking position, thereby improving the loading efficiency, and then the empty bearing material column can be added manually or by a robot.

[0028] In the utility model, the bearing ejecting mechanism can accurately eject the bearing from the storage position through the vertically movable bearing lifting plate, and ensures the smooth extraction of the bearing through the design of the lifting gap. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] In the present utility model, the bearing storage mechanism 11 includes a bearing storage turntable 111 and a bearing storage driving device 112 for driving the bearing storage turntable 111 to rotate; the outer periphery of the upper surface of the bearing storage turntable 111 is distributed with bearing material columns 113 for placing bearings; through the cooperation of the bearing storage turntable 111 and the bearing storage driving device 112, automatic circulation feeding of bearings is realized; when the bearing of a certain bearing material column 113 is taken away, the turntable continues to rotate, and the new bearing material column 113 automatically turns to the material taking position, thereby improving the loading efficiency, and then the empty bearing material column 113 can be added manually or by a robot.

[0058] In this embodiment, a third area 381 is provided between the first area 363 and the second area 364. When the bearing is pressed into the workpiece, the bottom end of the mounting seat 342 contacts the third area 381, and the contact surfaces between the third area 381 and the mounting seat 342 and the third area 381 are all smooth arc surfaces; thereby, after the connecting member 36 and the connecting member 34 are floatingly connected, they can be more stable when floating in the horizontal direction, and the floating process is smoother.

[0059] It is worth noting that when the bearing abuts against the workpiece and the bearing press-fitting drive device 32 drives the bearing press-fitting assembly 33 to continue pressing down to press the bearing into the workpiece, the floating between the connecting member 36 and the connecting member 34 stops, thereby achieving stability during the pressing of the bearing press-fitting assembly 33; and before that, under the action of the positioning member 35 and the connecting member 36's own gravity, there is a gap between the top of the first area 363 and the inner wall of the top of the floating installation space 343, and there is a gap between the bottom end of the mounting seat 342 and the third area 381, and the gap is used to achieve vertical floating between the connecting member 36 and the connecting member 34.

During this process, the gap between the top of the first area 363 and the inner wall of the top of the floating installation space 343 and the gap between the bottom end of the mounting seat 342 and the third area 381 gradually shrink until the floating between the connector 36 and the connecting member 34 stops.
